The conductive nano- particles have an average particle size along each dimension of less than 500 nm for nano- particles having an aspect ratio of less than 20:1 or have an average particle size along each dimension of less than 2000 nm for nano- particles having an aspect ratio of 20:1 or great- er. The conductive nanoparticles are foiined into hierarchical micro- and nano-sized aggreg- ates having re-entrant morphology. The coating is both superoleophobic and conductive and re- tains these properties even when stretched un- der strain to over 100%. The coatings may be produced with simple spray technology.
